摘要：研究了 4340 钢中回火马氏体和贝氏体组织对屈服强度的贡献。在 600 至 1000°F 范围内回火导致屈服强度降低的主要因素是碳化物粗化和蜂窝状结构的扩大。回火马氏体和贝氏体结构的屈服强度都可以通过单一关系用晶胞尺寸和弥散体分布来描述，其中采用 Orowan 模型来描述弥散硬化的贡献，使用 Langford-Cohen 模型来描述晶胞尺寸的贡献。 （作者）
Abstract : The contributions to the yield strength of tempered martensitic and bainitic structures was examined in 4340 steel. The principal factors that contribute to the reduction in yield strength with tempering in the range from 600 to 1000F are carbide coarsening and enlargement of the cellular substructure. The yield strength of both tempered martensitic and bainitic structures can be described in terms of cell size and dispersoid distribution by a single relationship in which the Orowan model is employed for the contribution from dispersion hardening and the Langford-Cohen model for that from cell size.
